PORTABLE PIERCING- DEVICE.

Specification of Letters Patent. Patrgfltgd 1 29 1921 Application filed December 6, 1918. Serial No. 265,621..

To all whom it may concern:

Be it known that I, Gnonon ILCONNOR, a

city of St. Louis and Stateof Missouri, have invented a new and useful Portable Piercing Device of which the following is a specification.

In the manufacture of clothingit is cus tomary to lay a largenumber of layers of cloth upona table, place a. pattern upon the top layer, and to provide the top layer with marks throughthe pattern toindicate where button holes are to be formedsbuttons to the sewed, and the like, and latter. the toplayer of cloth has been marked to takean awl. or

-similar tool and force it throughall of thef lowers of cloth to indicate the locations of the button holes to be formed, buttons to be sewed and the like, without having to .lay

, ingdevic'e that will be verycompact, having all of the parts in vertical axial alinement,

resulting in simplicity ofconstruction, durability, and efliciency.

With the above and other objectsinview, I

I the invention consists in the novel vfeatures oi construction,= combination, and; arrangement of parts, hereinafter described and finally'pointed out in the claims hereto appended.

Referring to the accompanyingdrawings forming a part of this specification wherein like characters of reference denote similar parts throughout the several views Figure 1, is a side elevation of a'piercing device constructed in accordancewith my invention, showing theypiercing tool in its uppermost raised position.

in carrying out the aim of my invention,

I employ a suitable base-plate 1 having a central opening 2 to enable an operator to readily see any markings on the piece 01 the lay and to readily and quickly place the p ercing device in proper position on the top pieceof the lay so that the piercing tool,

which will be hereinafter more clearly set forth can be positioned directly over any inarkmgadapted to indicate piercing of the ay.- p A suitable supporting head 3 having a; vertically ClISPOSBCl central opening 4 is supported asuitable distance directlyabove the opening 2, of thebase-plate 1 by means of suitablesupporting legs 5 which are preferably integral with the base-plate 1. The supporting head 3 is providedwith a suitably shaped hollow depending member 6 which extends to the lower plane of the baseplate 1 and is provided with a piercing tool receiving and guide opening 7 in axial alinement with the opening 4 of the supporting head 3. This tripod arrangement permits the operator to readily see the markings on the top piece of the lay through the opening 2 of the-base-plate 1 from any side of the device as is manifest. Atubular member 8 is suitably supported by the head 3, such as by threaded engagement with the inner wall ofthe opening 6, as clearlyshown in Fig. 3. The tubular member 8 is provided with a longitudinally slotted opening 9 having a I right angulanoiisetlO, at its. upper end, to

provide'a shoulder 11, as shown in Figs. 1 and 8.

' The tubular member 8 acts as a vertical guide, as will be more clearly apparent herelnafter. The tubular member 8 is provided with a suitable vertically adjustable gagecollar 12. Suitable retainingd'evices-B are employed for holding the collar 12 in any adjusted position, or elevation on the tubular member 8 as shown inFig." 3.

The rererence character I L designates a suitable electric motor having the vertically disposed armature shaft 15. The lower end of the motor 14 is provided with a suitable .neck16through which the armature shaft passes, as clearly shown in Fig. 3.

Asuitable toolystock 17 is suitablyfixed to through the tubular member 18 in axial and depends from the lower end of the armature shaft and is adapted to revolve therewith. i r

Atubular member 18 is suitably secured to and depend from the neck 16, of the motor 14, and is receivable within the tubular member 18, as clearly shown in Fig. 2. The tubular member 18 is provided with a plurality of sets of suitable ball bearings 19 which are spaced. apart by means of the spacing rings 20. The tool stock 17 it will be ob served, from Fig. 3, passes downwardly neck 16, of the motor 1&,'such as screws or like fastening devices. 1 When the tubular member 18 and tubular handle member 21 are assembled there is an annular space or chamber 23 formed between the two ele- :ments for the receptionof the tubular member 8 which is supported by the head 3, as clearly shown in Fig. 3.-

A set of end thrust ball-bearings 241 are employed at the upper end of the tool stock 17. The lower end of the tool stock 17 is provided with a suitable chuck 25 for.holding a suitable piercing tool 26, which tool is adapted to beforced through the lay orspread of cloth for accurately marking, by piercing each layer of cloth as the piercing tool passes through the same. I

From the foregoing description it will be readilyseen that I have provided a piercing device that will accurately pierce a lay or spread of cloth comprising a number of layers for indicating the locations of button holes to be formed, buttons to be sewed, and similar locations in the cloth or other material.

The tubular handle member 21 is provided with a set screw 27, which is adapted to engage in the slotted opening 9 for guiding the telescopic movement of the tubular members 18 and 21 and which screw further acts as a means to rest upon the shoulder 11 to hold the telescopic members in their extended position when desired.

A suitable switch 28 is secured to one of .the electric conductors 29 leading to the motor 14:, so that the motor may be quickly started or stopped, as desired.

' -The operation of the piercing device is as'follows: V

After a layer spread of cloth is laid out upon a table and the various piercings marked upon the top layer of material, the

operator places the device upon the material so that the piercing toolcomes '-directly over some ne attern marking. Theoperator positions 'the' device with the pierclng tool inits uppermost raised position, so that it will not engage the material to be pierced.

After the device has been positioned the piercing tool is lowered so as to pass com- 'pletelythrough' the guide opening 6 of the it appertains.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptionof the device to various conditions of use without departing from the spirit and scope of my invention and the terms.
